Algebra.Com's Answer #230370 by stanbon(75887) ![]() You can put this solution on YOUR website! A rocket is shot straight into the air at an initial velocity of 96 feet/second. The height of the rocket after x seconds is represented by the formula h = 96x – 16x2. What is the maximum height the rocket reaches? \n" ); document.write( "--- \n" ); document.write( "Max height occurs when x =-b/2a = -96/(-2*16) = 3 seconds \n" ); document.write( "---- \n" ); document.write( "The Max height = h(3) = 96*3-16(9) = 144 ft. \n" ); document.write( "============ \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( "============ \n" ); document.write( "6 feet \n" ); document.write( "144 feet \n" ); document.write( "180 feet \n" ); document.write( "240 feet \n" ); document.write( " \n" ); document.write( " |
